The Polar V650 provides feedback on your recovery time, and you have the possibility of sharing your ride details and route information. On top of that, the barometric altimeter in the bike navigation provides clarity in the mountains. You won't lose track quickly with the Polar V650. The route guidance ensures you can focus on spinning the pedals instead of paying attention to the route. Has the training gotten a bit out of hand? The V650 reckognizes dawn, and switches on the LED lighting automatically whenever the natural light isn't sufficient. Once you've returned home, use the Polar Flow web service to check your performance online. Here, you can analyse the results and compare them with other Polar users.
